When it comes to royally derailing IT, nothing trumps the stupidity of those whom IT is meant to serve. And though the verdict’s still out as to whether humanity is devolving toward Idiocracy, it’s certain that folks are continually finding innovative ways to screw up IT’s operations.

The last time we scrutinized that ultimate technology risk, the user, in “Stupid user tricks: Eleven IT horror stories,” David Letterman eventually called off the lawsuit. Then SWAT managed to defuse the letter bomb. And because that represented the most emotional response we received on any story last year, you knew we had to do it again. So here ’tis: more stupider user tricks.

By user we mean any schlub with network access or oversight who manages a brain fart loud enough to halt the network, compromise it, or in some other way cause harm to the enterprise, and thus the company's bottom line. Something that means at the very least a red face for several days, possibly a secret beating and swirlie administered by other employees in a darkened bathroom, even a Trumpesque directive to explore the outside world for the rest of one’s life.

So, take heed. Lessons await. And if you’ve had a run-in with userus stupidus, feel free to share the fallout.
